Systems for securing zipper closures

ABSTRACT

A zipper closure includes a first coil fixed to a first panel of an article and a second coil fixed to a second panel of the article, the second coil engagably securable to the first coil. A slide selectively engages and disengages the first coil and the second coil when a pull connected thereto is moved. A flap is fixed to the one of the panels and is releasably fixed to the other panel. A positioned on an underside of the panel is sized to receive the pull when the slider is in a first position. This holds the slider in place against forces acting on the zipper or article itself.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to and the benefit of U.S. Provisional Patent Application Ser. No. 61/588,229, filed Jan. 19, 2012, entitled “Systems for Securing Zipper Closures,” the disclosure of which is hereby incorporated by reference herein in its entirety.

INTRODUCTION

Zipper closures are used on articles of clothing, purses, luggage, sports uniforms, and other articles, to close two panels of material relative to each other. These panels may be the front panels of a jacket, the side panels of a purse, the panels of a suitcase, etc. In all instances, the zipper closure secures two elements to prevent opening and access to the interior. These zipper closures may be forced open due to excessive forces on the article or by the action of an unauthorized person. Regardless, existing systems to secure zipper closures are often inadequate for many applications. One such approach, often used in sky diving suits, requires placing a piece of tape across the coils of a zipper closure, in a path of travel of the zipper slider, under the zipper pull. When so located, the tape may prevent the zipper slider from being forced downward by external forces (for example, the extremely high velocity air attendant with sky diving). This approach is undesirable, however, because repeated use of tape may damage the sky diving suit material or stick to the coils thereby resulting in poor performance of the zipper.

DETAILED DESCRIPTION

FIG. 1A depicts an article of clothing 100 which in this case may be a sky diving suit. The article 100 includes two front panels 102 a, 102 b, and a zipper closure 104 for selectively securing the first panel 102 a to the second panel 102 b. The zipper enclosure 104 includes a first coil 106 a and a second coil 106 b, each fixed to a respective panel 102 a, 102 b. The zipper closure 104 also includes a pull 108 that actuates a slider (hidden). The slider may be moved up or down along the zipper closure 104 (by gripper and moving the pull 108) to selectively engage and disengage the coils 106 a, 106 b. The article 100 also includes a flap 110 or other zipper securement system to secure the pull 108 against external forces, thus ensuring the zipper closure 104 remains fixed. Various embodiments of zipper securement systems are described below.

FIGS. 1B and 1C are enlarged partial views of the article 100 of FIG. 1A, having a zipper securement system in open and closed (or unsecured and secured) positions, respectively. The flap 110 includes a pocket 112 sized and configured to receive the pull 108 when that element is in the uppermost position on the zipper closure 104. The pocket 112 is located on the underside of the flap 110 and is secured on at least two sides 114 to the flap 110, generally by stitching, very high strength fabric adhesives, or a combination thereof. The bottom edge 116 may also be secured to the flap 110. A top 118 of the pocket 112 may be configured and sized to allow easy insertion of the pull 108. This may include use of an angled upper edge at the top 118, as depicted. The flap 110 also includes securement means 120 such as hook-and-loop fasteners (commonly referred to VELCRO™), mating buttons or snaps, or other elements to releasably fix the flap 110 to the opposite panel (in this case, panel 102 a). In another embodiment, the flap 110 may define a slit and a button may be secured to the opposite panel 102 a, such that engagement of the button in the slit releasably secures the flap to the panel 102 a. The flap 110 is fixed to the opposite panel 102 b, proximate the coil 106 b with stitching, very high strength fabric adhesives, or a combination thereof. FIG. 1C depicts the article 100 with the zipper securement system in the closed position. When in the closed position, the flap 110 is positioned over the top portion of the zipper closure 104. The pull 108 is received within the pocket 112 and the securement means 120 holds the flap 110 in place. When in this position, the zipper closure 104 is prevented from being forced open.

FIG. 2 depicts an alternative embodiment of the pocket 112, having a curved top edge 118′. Other configurations of the pocket are contemplated. For example, the bottom 116 may be secured or unsecured to the flap 110. The pocket 112 may be formed of an elastic or semi-elastic material to ease insertion of the pull 108 therein. Additionally, the pocket may be formed from two or more discrete panels of material, as required or desired for a particular application.

FIGS. 3A-3C depict an article 300 having another embodiment of a zipper securement system. The system is configured as depicted in the preceding figures, accordingly, common elements (panels 302 a, 302 b; coils 306 a, 306 b; slider (hidden); and pull 308) are not described further. The zipper securement system depicted in FIGS. 3A-3C, however, includes two flaps 310 a, 310 b, to secure the zipper pull 308 in place. A first flap 310 b includes securement means 320 b such as those described above. The first flap 310 b is sized to fit underneath the pull 308 when the pull 308 is in the uppermost position on the coils 306 a, 306 b. With the securement means 320 b engaged, this first flap 310 b prevents the slider from being forced downward. This partially secured position is depicted in FIG. 3B. In this partially secured position, however, the pull 308 is still accessible, which could lead to undesired movement. In certain embodiments, however, this partially secured position may be sufficient to prevent movement of the pull 308. FIG. 3C depicts a secured position, where a second flap 310 a is folded over the pull 308, and securement means located thereon 320 a are fixed to the opposite panel 302 b. This secured position prevents movement of the pull 308.

The materials used in the zipper closure securement systems depicted herein may be any materials typically used in the manufacture of clothing or other articles on which the securement system is located. These may include nylon, polyester, rubber, GORE-TEX™, elastic, LYCRA™, etc. Additionally, although the above embodiments are described in the application of a sky diving suit, the systems may be used on other articles having zipper closure systems where inadvertent or unintentional movement of a slider is not desirable. These may include outdoor clothing or equipment, where zipper pulls may catch on tree branches or other elements. Also, the systems have application on luggage or bags to help disguise and further secure the zipper closure from unauthorized access. Additionally, securing the zipper pull as described herein may also prevent breakage to the pull, which may occur during handling (by automated baggage equipment, for example).

Additionally, the zipper securement system need not be located only at a top of a zipper closure. For example, multiple flaps and/or pockets may be located at various locations along a jacket flap on an article of clothing. This would enable the slider to be secured in multiple positions along the length of the zipper closure. Retrofit zipper closure systems are also contemplated. In such an embodiment, the flap depicted in FIGS. 1B-1C (or the flaps in FIGS. 3A-3C), may be releasably secured to both panels with securement means. This would allow existing articles to be improved with the inclusion of zipper securement systems.

While there have been described herein what are to be considered exemplary and preferred embodiments of the present technology, other modifications of the technology will become apparent to those skilled in the art from the teachings herein. The particular methods of manufacture and geometries disclosed herein are exemplary in nature and are not to be considered limiting.
